HelloI have 3 sites and i ant to interconnect them with OSPF. IOS feature set allows it. Pls look at the attachement.There are Cisco 3750 switches stacks on each site. The problem is site 1 has two stacks connected via trunk line. I need to keep this...
HiI have several sites connected with each other by the ISP. Each site has a 10Mbps FastEthernet port pointing to the ISP cloud. I have GRE tunnels from one site to each other with OSPF running inside.I'd like to implement QoS , the question is what ...
Hello everybodyWe are implementing reserve server farm (SERVERFARM2 at the picture) and we want to connect the farms via the 10G link. 10G is the requirement.I have a server vlan and several clients vlans. Inter vlan routing is provided by 3750G LAN ...

Thank you for your reply.I suppose I will additionally have to declare all the vlans, except OSPF backbone vlan, passive-interfaces. Otherwise OSPF will form neighbour relationships on each vlan across the stack. So the setup will look like this:Stac...
Inter vlan routing is done by the 3750 switches themselves, there is no router-on-a-stick setup here.Site 2 and 3 are new ones, in fact, there is only one link at the moment - the link between site 1 and 2. Other links will be ready soon.Routing betw...
I've got few more questions.I've read that fair-queue is enabled by default on low-speed interfaces(less than 2Mbps) and is working best at low speeds.What about10Mbps interfaces? Are there any disadvantages on applying such policy-map (with fair-que...
Thank you for your replies!I have some other sites with 2Mbps uplinks where my outside interface speed is set to 10Mbps or even 100Mbps. Traffic is simply rate-limited by the ISP at 2Mbps. So there is sense to use 2Mbps shapers there?I'm also unsure ...
Pls correct me if I am mistaken but as far as I know the ToS bits of the original packet are copied to the GRE outer header.In later IOS versions it is happening by default. Older versions required the qos pre-classify command.http://www.cisco.com/en...
